Real-Time Ethereum Blockchain Analytics Dashboard

Project Overview

Ethereum Insights is a sophisticated React-based application that provides in-depth, real-time visualization of key Ethereum network metrics. By leveraging the Alchemy Web3 API, the dashboard offers granular insights into blockchain dynamics through three critical metrics.

Technical Architecture

Data Source

• Provider: Alchemy Web3 API
• Network: Ethereum Mainnet
• Token: USDC (ERC20 Token)
• Endpoint: Ethereum JSON-RPC via Alchemy Core

Key Performance Metrics

1. ERC20 Token Transfer Volume Chart

• Data Point: Total USDC transfer volume per block
• Calculation Method:

  Total Volume = Σ(individual transfer values)
  

• Retrieval Mechanism:
  • alchemy.core.getAssetTransfers()
  • Filters for ERC20 category
  • Specific contract address: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 (USDC)

2. Base Fee per Block Chart

• Data Point: Base fee in Gwei
• Conversion Formula:

  Base Fee (Gwei) = BaseFeePerGas / 10^9
  

• EIP 1559 Significance:
  • Implements dynamic block sizing
  • Provides more predictable transaction pricing
  • Introduces burn mechanism for ETH

3. Gas Usage Ratio Chart

• Data Point: Percentage of block gas capacity utilized
• Calculation Formula:

  Gas Usage Ratio = (gasUsed / gasLimit) * 100%
  

• Blockchain Efficiency Indicator:
  • Shows block congestion levels
  • Helps predict transaction confirmation times

Technical Implementation Details

Fetch Strategy

• Blocks Fetched: Latest 10 blocks
• Update Interval: 20 seconds
• Retry Mechanism:
  • Maximum 3 retries
  • Exponential backoff delay
  • Prevents API rate limiting

Error Handling

• Custom fetchWithRetry() function
• Graceful error logging
• Prevents application crash during data retrieval

Performance Optimizations

• Asynchronous data fetching
• Responsive container for cross-device compatibility
• Animated line charts for smooth user experience

Dependencies

Frontend

• React
• Recharts (Visualization)
• Material-UI (Component Styling)

Blockchain Interaction

• Alchemy Web3 SDK
• Ethereum JSON-RPC
